DEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملString cosmology and inflation.
Following a suggestion by Gasperini and Veneziano, that String Cosmology can be reconciled with Inflation and, hence, with the Standard Big Bang, we display an analytical solution which possesses four interesting properties: (1) it is non-singular; (2) it distinguishes the dynamics of the external scale factor, a(t), from that of the internal one, b(t); (3) it exhibits a non-monotonic behavior ...
متن کاملInflation and String Cosmology
Inflationary theory is already 20 years old, and it is impossible to describe all of its versions and implications in a short talk. I will concentrate on several subjects which I believe to be most important. First of all, I will give a brief review of the first versions of inflationary theory, from Starobinsky model to new inflation. Then I will describe chaotic inflation, the theory of quantu...
متن کاملDilaton-driven Inflation in String Cosmology
I present an outline for cosmological evolution in the framework of string theory with emphasis on a phase of dilaton-driven kinetic inflation. It is shown that a typical background of stochastic gravitational radiation is generated, with strength that may allow its detection in future gravity wave experiments. Present address: Department of Physics, Ben-Gurion University, Beer-Sheva 84105, Isr...
متن کاملString Theory and Cosmology
We discuss the main cosmological implications of considering string-loop eeects and a potential for the dilaton in the lowest order string eeective action. Our framework is based on the eeective model arising from regarding homogeneous and isotropic dilaton, metric and Yang-Mills eld conngurations. The issues of innation, entropy crisis and the Polonyi problem as well as the problem of the cosm...
